BIOD 210 EXAM 5 (Genetics) Questions and Answers | Latest Update 2026/2027 | Graded A+ - Portage Learning. Consider the following DNA sequence: 3'-AAC TAC TGT GTA -5' •a. Write out the complementary RNA sequence, including the 5' and 31 b. Translation starts on which end of the RNA (5' or 3')? c. Identify the start codon in the complementary sequence you wrote in part a. of this question. Your Answer: A. 5'-UUG AUG ACA CAU-3 t B. translation begins on the 5' end of the RNA strand C. AUG a. 5'-UUG AUG ACA CAU -3' c. AUG True or False: Transcription of DNA into mRNA requires an RNA primer. False Question 3 3/6 pts Why must the DNA within eukaryotes be complexed with histone proteins, but not in bacteria? What happens to these complexes during DNA replication? Your Answer: In eurkaryotic cells, DNA is condensed with the proteins to form chromatin. Then during the DNA replication process the chromatin relaxes, and after replication the DNA condenses back around the histones again. There is a huge amount of DNA within a eukaryotic cell, and it needs to be stored within a tiny space within the nucleus. Therefore, it is complexed with proteins into chromatin that help to condense it into an extremely compact form. When it is time for DNA replication to occur, the complexes relax due to the proteins dissociating from it. Then as soon as replication is complete at a certain point, the DNA winds around the histone proteins and recondenses. nnt answered 10 / 10 pts Question 7 2/ 2 pts True or False: A silencer or enhancer element is almost always located immediately upstream of the gene that it is affecting. False Question 8 2/ 2 pts True or False: Once a polymerase is moving forward along a nucleotide chain, the ability to stall and reverse direction if things go wrong is called proofreading.
